The university strongly recommends that you enroll more than one device in this service. This way, if your device becomes lost, stolen, or reset to factory conditions you will be able to use a backup device to re-enroll the affected device.

If you are using a Duo hardware token (hard token), you will need to enroll a phone as well as the hard token. This phone does not need to be used to authenticate, after enrolling the phone, you will be able to authenticate with the hardware token.

This phone number cannot be a public phone, for example, the main line to an office which many others can access.

If you need assistance enrolling your phone or to find more information about hardware tokens, please call the UT Service Desk at 512-475-9400 or visit the UT Service Desk located in the lobby of the Flawn Academic Center.
